IMPROVEMENT IN LA'RD-OILYLAMPS.

. Specification forming part of Letters Patent No. 181,722, dated August29, 1876; application filed February 14, 1876.

To all whom it may concern:

Be it known that I, JOHN RoEMER, of (Jhumpion, in the county ofMarquette and State of Michigan, have inventeda new and ImprovedLard-Oil Lamp, of which the following is a specification:

My invention consists of pipes for receiving the heat of the flame, andconducting it down into the oil-chamber for warming the oil; the objectbeing-to make lard-oil lanterns capable of use in very cold weather. Iprefer to mount a hollow drum on the pipes over the flame for obtainingthe heat; but good results are obtained without the drum.

Figure 1 is a sectional elevation of my improved lantern with a drummounted on the pipes. Fig. 2 is a top view, and Fig. 3 is a horizontalsection taken on the line 3 y of Fig. 1. I

Similar letters of reference indicate corresponding parts.

Ais the oil-chamber of thelamp, from which two pipes, B, of copper orother good heatconducting metal, extend up a suitable distance above theburners G, and have a drum,

D, mounted on them, as shown; or they may bend over, so that the upperends terminate directly over the flame, opening downward, so as toreceive currents of hot air, and conduct the-heat down into theoil-chamber, to keep the oil in a fluid state.

When the drum is used I prefer to connect one pipe with the-interior ofthedrum, and arrange the other to pass up throughit, so that, by havingan opening intothe drum, a current will be established down one pipe andup the other.

I am aware that it is not new to provide a lamp with a tube havingfunnel-mouth over the burner, and extending through the oil; but

What I claim is- 1 The combination, in a lard-oil lamp, of the drum Dand oil-chamber A, connected by heatconducting air-pipes B,substantially as and for the purpose specified.
